9 Facts About Blood Transfusions

source
1

Blood transfusion is the process of transferring blood or blood products into one's circulation intravenously.

Blood is a body fluid in humans and other animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells.

Intravenous therapy is the infusion of liquid substances directly into a vein.

A blood product is any therapeutic substance prepared from human blood.

Early transfusions used whole blood, but modern medical practice commonly uses only components of the blood, such as red blood cells, white blood cells, plasma, clotting factors, and platelets.

Red blood cells-- also known as RBCs, red cells, red blood corpuscles, haematids, erythroid cells or erythrocytes, are the most common type of blood cell and the vertebrate's principal means of delivering oxygen to the body tissues—via blood flow through the circulatory system.

Platelets, also called thrombocytes, are a component of blood whose function is to react to bleeding from blood vessel injury by clumping, thereby initiating a blood clot.

White blood cells are the cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders.

Red blood cells contain hemoglobin, and increase iron levels by improving the amount of oxygen found in the body.

Hemoglobin or Haemoglobin ; abbreviated Hb or Hgb, is the iron-containing oxygen-transport metalloprotein in the red blood cells of all vertebrates as well as the tissues of some invertebrates.

White blood cells are not commonly used during transfusion, but are part of the immune system, and fight infections.

The immune system is a host defense system comprising many biological structures and processes within an organism that protects against disease.

Plasma is the liquid part of the blood, which acts as a buffer, and contains proteins and important substances needed for the body’s overall health.

Proteins are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues.
